Sludge Grinders

Franklin Miller grinders play an important role in enhancing sludge processing and protecting sludge processing equipment. These grinders are used in wastewater treatment, industrial waste and septage handling applications.

Sludge processing is an operationally challenging part of the wastewater treatment process. Sludge is often difficult to process and tough on equipment. Pumps, centrifuges, belt filter presses, nozzles, digestors and trickling filters can have frequent maintenance problems and downtime even in plants with fine headworks screening.

Franklin Miller sludge grinders are designed for a variety of flows. These unit are installed directly inline via standard flange connections and quickly go to work reducing over-sized solids that can cause jamming and damage to pumps, filter presses, nozzles and process equipment. Whether in a once through or recirculated configuration our grinders produce better digestion, less energy use, and longer useful life for downstream processes.

The SUPER SHREDDER® inline disintegrator reduces tough solids entrained in pipeline systems. This unit combines world-class size reduction capabilities with a streamlined, easy-to-maintain design that features only two working elements. The SUPER SHREDDER is ideal for applications requiring a heavy-duty size reduction processor that can handle high flows with minimal headloss.

The SUPER SHREDDER utilizes a low speed and high torque action to chop, grind and shred solids into fine bits that can be easily processed by downstream equipment. Its innovative open-center spherical rotor design maintains a high percentage of open area—making this unit practically invisible to the flow. In fact, it can handle higher flows than any other inline grinder available.

With only two cutting elements, SUPER SHREDDER construction and maintenance is greatly simplified. The cutters are constructed of stainless steel with a heavy abrasive-resistant fused coating precisely applied to all cutting surfaces. These corrosion-resistant cutters provide long dependable service without the embrittlement associated with hardened alloys. With its bidirectional cutters, wear is further reduced via automatic reversing of the unit’s direction of rotation. Two convenient cartridges house the unit’s seals and bearings. Each cartridge consists of a primary seal, a severe duty mechanical seal, oil seal, heavy duty tapered roller bearings and stub shaft. This seal design has proven highly dependable and easy to maintain.


TASKMASTER® inline grinders employ a powerful twin-shaft mechanism and CUTTER CARTRIDGE® technology to reduce solids in pipeline systems. These versatile processors reduce rags, plastics, wood, tampons, sanitary napkins, sanitary wipes and more. They are invaluable in plant operations worldwide, keeping systems flowing, reducing pump downtime and protecting dewatering equipment, such as centrifuges, filter presses and more.

TASKMASTER inline grinders are available for 4” through 30” pipe sizes. These units feature severe duty mechanical seals, heat-treated hexagonal shafts and a direct, cycloidal gear drive. Each unit is supplied with an S260 Automatic Reversing Controller.
